Esthetics / design quality: we wanted to create a landmark. Anodized top aluminum, long design lines and smooth curves that all together feel perfect in the hand. It took two years to finish this masterpieces, which is eye catching and very new to the vape world. Practical use: great design must be practical to be accepted by consumers. Our one-click-system delivers this promise. Strong magnets keep both parts strongly together. Opening the body to insert or change the refill caps could not be easier. Environmental impact: Tobacco and nicotine free aluminum caps, backed by a clever, free of charge recycling system. Filled with signature flavors.
